Abstract

The present invention relates to a building management system and a method thereof, the system including: a building management controller for controlling the building management by integrating power distribution, an air conditioning system, energy management, etc., and a BACnet gateway for transmitting control messages of the multi-type air conditioners which are received through the Internet by converting the message to be compatible with the BACnet protocol. Accordingly, it is capable of facilitating monitoring and controlling of the multi-type air conditioners whenever and wherever by a user by using only an IP address, thereby overcoming the conventional limitation in a communication distance between the BACnet gateway and a local controller.

Claims

1. A building management system, comprising:

a BACnet gateway connected to one or more air conditioners; and

a web service module connected to the BACnet gateway which provides data from the one or more air conditioners to a terminal through the Internet.

2. A building management system according to claim 1, wherein the web service module comprises a data extraction unit that receives the data from the one or more air conditioners.

3. A building management system according to claim 2, wherein the web service module comprises a web page generation unit that generates a web page which displays the data received from the one or more air conditioners.

4. A building management system according to claim 3, wherein the web service module comprises a web server which transfers the web page to the terminal through the Internet using an HTTP protocol.

5. A building management system according to claim 2, wherein the data extraction unit periodically extracts the data from the one or more air conditioners from a database.

6. A building management system according to claim 1, wherein the web service module receives commands which control the one or more air conditioners from the terminal through the Internet.

7. A building management system according to claim 6, wherein the web service module sends the commands to the one or more air conditioners via the BACnet gateway.

8. A method for managing one or more air conditioners, comprising:

receiving data from one or more air conditioners via a BACnet gateway;

generating a web page which displays the data received from the one or more air conditioners; and

transferring the web page to a terminal through the Internet.

9. A method according to claim 8, wherein the web page is transferred to the terminal using an HTTP protocol.

10. A method according to claim 8, wherein receiving the data comprises receiving the data from a database.

11. A method according to claim 8, further comprising receiving commands which control the one or more air conditioners from the terminal through the Internet.

12. A method according to claim 11, further comprising sending the commands to the one or more air conditioners via the BACnet gateway.
